Got tow copies of a mkv film. One of them the quality isnt good but the sound is in english, the other file perfect picture but its hardencoded in french. Using mkvmerge ive sucessfully extracted the enlgish audio only and saved as a .mp file. Im running the perfect picture one with virtualdub latest one. Under audio selected audio from s file and picked the file i extracted earlier. However now when trying to merge to two together and theoretically overriding the french audio with the english one fixing my issue but virtual dubs bring up an error message saying : no decompressor could be found to decompress the audio format"
Is their a way of fixing this?
